ABSTRACT:
An energy apparatus for supplying breathable gas in an aircraft has a source of pressurized breathable gas and a feed pipe for feeding gas to the feed regulators of individual emergency equipments. The apparatus includes a test system for checking proper operation without consuming pressurized gas. The system includes an atmospheric air compressor having its outlet in communication with the feed pipe via a two-positioned selector constituted so that at rest it connects the source (generally oxygen under pressure) to the pipe and separates the pipe from the compressor, and when in a position to which it is brought on receiving compressed gas from the compressor, it separates the pipe from the supply.
